WG10 Proposal:

to be adressed to the 61850-6-100 (need a realistic date)6-100 states that n:1 relationship between LNodes and LNs is allowed and supported. No need to change the SCL scheme for this.

Estimated Completion:
End of 2023

No
To discuss in WG10:
No
Short Proposal:

Discussed with TF SCL function modelling.

Standard(s):

IEC 61850-90-30

Needs More Information:
No
Assigned TF:
61850-6-100 (Function modeling)

Description

The Standard requires a one to one mapping between LNode and LN. This creates serious limitations. Examples:
1. Let us assume vendor makes use of GGIO and represent a 32 bit BI/O Interface Card in the IED with the LN BIO32GGIO1. Now in my Substation section I define two Functions with Fun1/BIOGGIO1, Fun2/BIOGGIO2. Fun1 and Fun2 are two very different functions, but I have only one BIO card in my IED. Now I would like to map the LNode Fun1/BIOGGIO1 to LN BIO32GGIO1 and Fun2/BIOGGIO2 also to LN BIO32GGIO1. Naturally they use distinct Data Attributes.

2. It is easy to find a similar example for MMXU. Power Measurement and Current/ Voltage Measurement can be used in different Functions in the Single Line, but are using the same LN MMXU.
